  <div class="info">
    <i>ol.control.Bar</i> can be nested in a sub-bar using an <i>ol.control.Toggle</i> to control its activation.
    <ul>
      <li>
        <i>toggleOne</i> option makes only one control activated at once.
      </li>
      <li>
        <i>autoDeactivate</i> option will deactivate all controls in the sub-bar when this is deactivated.
      </li>
    </ul>
    Options of the <i>ol.control.Toggle</i> enables the sub-bar activation:
    <ul>
      <li>
        Use the <i>bar</i> option of the <i>ol.control.Toogle</i> to set the sub-bar you want to display.
      </li>
      <li>
        The <i>autoActive</i> option enable you to automatically activate a control when the sub-bar is shown.
      </li>
